Wagga has recorded its first coronavirus cases since April with a family of four confirmed to have the virus.
The family has been isolating since returning from Victoria on July 25, when they visited Melbourne.
Murrumbidgee Local Health District officials said a 52-year-old woman has mild symptoms of the virus.
Two people in the family aged in their 20s and their baby have all tested positive for the virus but are asymptomatic.
Health authorities could not confirm how long the family had been in Melbourne or what the purpose of their visit was, only that they had left NSW since the border closure permit system was introduced.
The family had a valid permit to cross the border.
MLHD medical director Len Bruce thanked the family for "doing the right thing".
Authorities say the family have been self-isolating correctly and that no further contact tracing is required.
